c. Search by Registered Agent

Another way to look up an LLC in Louisiana is by searching for a Louisiana registered agent. A registered agent is an individual or business that agrees to receive legal documents on behalf of the LLC.

On the Secretary of State's website, click the "Registered Agent" tab on the commercial search webpage.

From there, you can search for the desired registered agent and access further details by clicking the "Details" button.

Ensure to provide as much detail as possible about your query to facilitate a comprehensive response.

This method suits non-urgent inquiries, allowing the office staff to compile the necessary information and respond accordingly.

• Legal Databases: Platforms like LexisNexis or Westlaw can provide legal information on LLCs, including litigation history.

How to Check If A Business Name Is Trademarked in Louisiana?

To check if a business name is trademarked in Louisiana, search the US Patent and Trademark Office (USPTO) website. This search will reveal if the name is federally trademarked.

Also, checking with the Louisiana Secretary of State can help identify state-level trademarks.

Here's how to proceed:

1. Use the Federal Trademark Search (US Patent and Trademark Office (USPTO) Website)

The first step is to visit the USPTO's official website and use the Trademark Electronic Search System (TESS).

This database includes all registered trademarks and pending applications at the federal level.

Searching here will help you identify if your desired business name or a similar one is already trademarked, potentially leading to legal issues or rejection of your trademark application.

2. State-Level Trademark Search

For state-level trademarks, you should check with the Louisiana Secretary of State.

Louisiana provides resources for searching business entities and registered trademarks within the state.

Visit the Louisiana Secretary of State's business search page. This search primarily identifies business entities rather than trademarks.

According to the Louisiana Secretary of State's annual report, in 2024, the business search tool facilitated over 50,000 searches, underscoring its utility in navigating state-level business registrations and trademark inquiries.

But it's crucial to ensure that another business does not already use your desired name in a similar capacity, which could also lead to trademark conflicts.

3. Consultation with a Trademark Attorney

Given the complexities of trademark law and the potential for overlap between state and federal registrations, consulting with a trademark attorney can provide valuable insights and guidance.

An attorney can help you navigate the search process, interpret results, and advise on the likelihood of trademark registration success.

Reasons to Perform a Search
